- Heath Hayes let me ride his virtually brand new YZ450F. I didnt want to push too hard on a bike I didn't want to break, and this was only my 3rd time riding a modern 4 stroke. Sign me up!
Hi Brian, upon doing a little nostalgic video watching this evening about YZ250’s, 99 model specific as I owned one. I’ve run into your video. Just a couple of questions, you said in the video that you’ve owned it for 25 years, and I’m curious if you bought it brand new ? If so did you run it in per the owners manuals instructions, or just get on and go ? I ask this specific question as all the other videos are just reviews of second hand bikes. If memory serves me correctly, after the run in procedure, you should lower the main jet one size (should have come in the spares kit if bought new) and I’m wondering how people actually read their manuals and follow what it says to do.
@@mickeyreed9628 was a long time ago but did buy it new. On 2 strokes over many years breakin was pretty non existent. Although i raced locally pro when younger, when i bought this one i hadnt ridden in about 5 years so my breakin period was just a “getting used to it” period. Once you ride it couple times easy you will not hurt it. In fact, for most normal humans, you probably cant ride it hard enough to hurt it even at break in. Now if you just tap it out on the street or dirt roads i’d take it easy for a couple 20 min periods. When i raced competitively and rebuilt an engine i never broke them in just run it.
Lap battles are fun! I've done a few between new and old bikes as well, I think familiarity with both plays a big part, as well as how tough the track is (newer bike suspension is more forgiving). Let's face it there are just some jumps I'm not going to go for on a 1980s bike! But your result backs up what I've seen as well - a new bike isn't going to automatically make a 20 second a lap time difference for most of us mortals! You should try to spend a day on a 450F and then give it another shot though, I'll bet those time differnces would flipflop.
Im sure they would. The bike is so smooth and fast, found the lines in the corners well, and was set up for a much taller and heavier guy than me. Plus its not my bike and i didn’t want to crash and break it.

I've opened your channel and I've noticed that you are that rider who made those videos about the SSS conversion I watched some time ago. I think that your current fork must have improved the performance of your bike a lot compared to the old 46 mm. I have a '01 YZ 250 with that OEM fork and when I try more modern bikes they feel much faster just because of the suspensions, especially because of better forks.
@@MVPever It took a little while to get them working well since they came off a 2008 YZ450 and the PO of the forks and shock had them revalved by factory connection and they had no rebound damping. I revalved close to the stock YZ250 valving. The forks inner cartridges were also worn and inner seals were bad. Once i got it all worked out they worked well.
I haven’t ridden a thumper in a long time
Yea, only my 3rd time. Other than my XR75! Check it out.
